HOLDING- ATTACHMENT FOR SOUND RECEIVERS.

Application filed March 11, 1922. Serial No. 543,115. 7

7 erence marked thereon;

This invention relates to means for supporting sound receivers particularly those known as head receivers which are used by telephone operators or persons receiving wireless messages.

It is the principal object of my invention to provide a holding attachment to which the receivers may be readily fastened and which will permit easy and rapid adjustment of the receivers.

It is another object of my invention to provide an attachment in which the supporting or head band is light and free from parts which readily catch the operators hair.

These and other objects will be apparent after a study of the annexed drawing 7, and accompanying specification, in which:

Figure 1 is a view of the holding attachment showing two receivers carried thereby, one of the receivers being turned at right angles to the other in order to show certain details.

Figure 2 is a top plan view of the head band which is shown in Figure 1.

Figure 3 is a side view of the head band shown in Figure 1.

Figure 4 is a fragmentary sectional view through the casing of the receiver on the line 4/4 of Fig. 1 showing the manner in which the receiver is carried in the saddle.

In the different figures, 1 illustrates a head band having its outer ends 2 and 3 formed outwardly, forming one member of a gripping device. The other member of the gripping device consists of members 4 and 5 which are preferably integral parts of the central portion of the band 1. These portions 4 and 5 are formed outwardly above the members 2 and 3 in spaced relation therefrom. The members 2, 3, 4 and 5 have holes 6 therein and as these members are formed in normal position, the holes 6 are in missaddle 8 which carries a receiver 9 through the medium of pins 10 shown in Figure 4. The receiver 9 has the usual terminals 14 to which the conductor cords are attached; After the stud 7 has been fastened to the saddle 8, the end is passed through the holes 6 in the pair of members 2 and 4, it being understood that a slight pressure of the fingers on members 2 and 4 springs them so thatthe holes 6 are in alignmentwhereby the stud 7 may be readily passed through, but when the force is removed from the members 2 and 4 or one of them, these mernbers spread, thereby gripping the stud 7 and holding the receiver in any given set position. It will thus be seen that the grip ping means above described provides a very rapid and positive adjustment for the receiver 9. It-might occur that in adjusting a receiver, the operator accidently springs the members 2 and 4 with relation to each other so that the stud 7 would fall accidently out of theholes and the receiver might become broken by an accidental fall. to prevent an accident of this kind, the end of the stud 7 is threaded and a headed screw 11 is screwed therein, thus forming a stop for the stud 7 Since the screw 11 or its equivalent can be readily loosened from the stud 7, it will be seen that'the assembly of the receiver to the band can be quickly accomplished.

The band 1 is lightened by having considerable of its central portion punched out as indicated at 12. The entire inner surface of the head band 1 is left perfectly smooth so that there are no extending parts to catch in the operators hair or head-dress.

In order to support the receiver cord I have provided aperforation 13 in the saddle, through which a receiver cord support may be fastened. It is usually the practice in making receiver cords to leave an end of the braid extended for this purpose and this eX- tended braid end may be fastened through the perforation 13. It is to be understood that the perforation 13 may be placed in the end of the band 1, but since the receiver as neat as where this cord end is attached to a saddle as described.

While I have shown a preferred form of a holding attachment it will be apparent that certain changes may be made in the details In order without departing from the spirit of my invention and the scope of the appended claims.

Having thus described my invention, what I claim is:

1. In a device of the class described, a one piece metallic head band having each end bent outwardly and a hole inserted therein to form one member of a gripping means, a member having a hole therein thrown downwardly from the material of the band to a point in spaced relationship to said upturned ends forming cooperating members to complete said gripping means, a saddle having means for carrying a sound receiver and a stud fastened to' said saddle and adapted to be passed through the holes in said gripping means whereby the stud and receiver may be held in any position.

2. In a device of the class described, a one piece metallic head band having an end bent outwardly and a hole inserted therein to form one member of a gripping means, a member, having a hole therein, thrown downwardly from the material of the band to a point in spaced relationship to said upturned end forming cooperating members to complete said gripping means, a saddle fitting around the periphery of the sound receiver and having pins for engaging and adjustably supporting the receiver, said saddle having an elongated stud adapted to be held by said gripping means after the stud has been passed through the holes therein.

In testimony whereof, I afliX my signature.
